Section 1: Introduction H 2 O 2 Monitoring Data (H2O2.DAT) Hourly or sub-hourly H 2 O 2 measurements at one or more monitoring stations Chemical Transformation Data (CHEM.DAT) Species-dependent chemical transformation rates for each hour of a diurnal cycle 1-39

Section 1: Introduction Table 1-5 (Concluded): Summary of Input Data Used by CALPUFF Hill Data (HILL.DAT) Hill shape and height parameters in CTDMPLUS format for use in the subgridscale complex terrain module (CTSG) CTSG Receptors (HILLRCT.DAT) Receptor locations and associated hill ID in CTDMPLUS format Subgrid Scale Coastal Boundary Data (COASTLN.DAT) File containing X,Y coordinates of subgrid scale coastlines to be treated by CALPUFF Boundary Data for Diagnostic Mass Flux Option (FLUXBDY.DAT) File containing X,Y coordinates of boundaries used to evaluate mass transport Because of the similarity between CTDMPLUS and the CTSG option within CALPUFF, an input option is provided for hill data and the associated receptor data in files produced for CTDMPLUS. These files, HILL.DAT and HILLRCT.DAT can be read by CALPUFF without modification, to specify all CTSG input requirements. Two additional input files, VD.DAT and CHEM.DAT, contain diurnal cycles of user-specified deposition velocities and chemical transformation rates, respectively. These files are necessary only if the user wishes to substitute the values normally computed internally by the deposition and chemical models with sets of time-varying but spatially-uniform externally specified values. The optional input file, PROFILE.DAT in the CTDMPLUS or AERMOD format can also be used to provide vertical profiles of observations of σ v and σ w . These parameters can be used to compute the plume dispersion coefficients σ y and σ z . CALPUFF can continue a previous simulation using an optional restart file (RESTARTB.DAT). The restart file contains all of the puff variables at the end of the previous run needed to allow the model to continue the simulation. The restart file used as input of a continuation run must be generated as the output restart file in the previous CALPUFF simulation. The restart file is an optional file. CALPUFF contains a subgrid scale coastal effects module that allows a parameterization of the Thermal Internal Boundary Layer (TIBL) at scales smaller than the grid spacing. The user inputs the X,Y coordinates of one or more coastlines in an optional file called COASTLN.DAT. 1-40

Because <strong>of</strong> the similarity between CTDMPLUS and the CTSG option within CALPUFF, an input option<br />

is provided for hill d<strong>at</strong>a and the associ<strong>at</strong>ed receptor d<strong>at</strong>a in files produced for CTDMPLUS. <strong>The</strong>se files,<br />

HILL.DAT and HILLRCT.DAT can be read by CALPUFF without modific<strong>at</strong>ion, to specify all CTSG<br />

input requirements.<br />

Two additional input files, VD.DAT and CHEM.DAT, contain diurnal cycles <strong>of</strong> user-specified deposition<br />

velocities and chemical transform<strong>at</strong>ion r<strong>at</strong>es, respectively. <strong>The</strong>se files are necessary only if the user<br />

wishes to substitute the values normally computed internally by the deposition and chemical models with<br />

provide vertical pr<strong>of</strong>iles <strong>of</strong> observ<strong>at</strong>ions <strong>of</strong> σ v and σ w . <strong>The</strong>se parameters can be used to compute the<br />
